Environment Canada has released a special warning for hot and humid weather this week, with temperatures expected to soar into the mid-30s. But it’s going to feel even hotter.

A blanket of warm air is expected to settle over southern Ontario Monday night, and while the temperatures will stay in the 30s, Environment Canada warned the humidex will hit 40 and above.

Monday will see a high of 28C in Toronto, inching to 33C on Tuesday and hitting the week’s high of 34C on Wednesday. The first day of summer, on Thursday, will have a slight dip to 32C, and give way to cooler temperatures for the weekend.

In such high heat, Environment Canada advises people to stay inside or in the shade, to forgo physical activity outside and to drink plenty of water.

The City of Toronto often opens up air-conditioned oases called “cooling centres” across the city during extreme heat. In the past, these locations have included the downtown Metro Hall on John St., the East York Civic Centre on Coxwell Ave. and the Etobicoke Olympium on Rathburn Rd.

The city has not yet said whether these locations will be made into public cool-down zones.

Dog owners are reminded to shorten walk times, refill Fido’s water bowl and to keep pets out of parked cars.
